The very first MiniDisc (MD) unit on the market. Rather bulky, it had a lot of on-device controls, which turns out to be very useful since this unit did not support remotes. It also had a front loader instead of the clamshell seen in later devices for inserting discs.
Not ideal as a player today. It's quite heavy and bulky, with poor battery life. It is also rather collectable (being the first recorder) and you can get a much more practical netMD device for a lower price.
Display only lights up when plugged into AC power.
These days, the BP-MZ1s from the era are all dead. Currently, you can get 3D-printed shunts that allow this unit to be powered by modern lithium-ion 18650 cells.
Please see Modern Batteries for more information and links.
If using labels, do not use embossed (raised lettering) forms. They will get stuck when ejecting. It's a pain and a process to get the MD out, and will likely ruin the label.
